An AI developer encountered a significant data loss issue when instructing a model to use literal TAB characters as field separators, as the model instead outputted the word "<TAB>". This misinterpretation led to 79% of the data being discarded because the parser was configured to detect actual tab characters, not the literal string. The developer identified that the core problem was conflating unparseable data (format errors) with ungrounded data (hallucinations) in the model's error reporting. Solutions involved providing a visual example of the desired separator (a pipe symbol '|') and using a non-existent name in the example to prevent the model from treating it as actual data, alongside implementing more granular failure detection.
